DESICCATING-MACHINE.

Bpecication of Letters Patent.

Patented Nov. 2a, 1914.

Application 'filed november 1, 1913. Serial No. 798,611.

To all whom 'it may concern l Vlic it known that I, Lnamn l. Mien, a` citizen ,of the United States, residing at Chicago, in the county of Cook and State of llllinois, have invented a certain new and useful improvement in Desiccating-ll'la chinos, of which the following is a specification. i

My invention relates to desicoating ma chines and applies more particularly to the desiccz. tion of milk or other fluid toed products.

The object of the invention primarily is to provide a continuously operating appa ratus in which the entire process is automatic and manual handling of the product is eliminated.

Another object is to render it possible to accomplish desiccation in a single seltcontained machine instead ot' in a buildingt Structure or a room or chamber constitutingpart ol." a stationary building.

As contributing to the general object of the invention, it is my purpose to provide. a comparatively small and light machine capable ot ready inspection both internally and externally; also to provide means whereby the dcsiccating product may be .removed from the machine pneumatically, thereby renderingl conditions sanitary both as regards the product and the attendant and reducing the amount oil attention neces sary.

l accomplish my objects by the mecha nism illustrated in the aecomlmnying drawings, in wbichm 'f `l i Figure I1 is a longitudinal sectional ele vation of the complete machine. The plane ot section is indicated by the line tml, Fig. Fig. 2 is an cud-elevation of the machine looking toward the le'lt in llig. l. Fig. 3 is a sectional elevation on the line -3 Fig. l. Fig. il is a longitudinal section showing the construction at the ends of the machine, the plane ol section being indi; cated by the line ^l-'le Fig. 2.

Similar numerals rclcr to similar' parts throughout the several views.I

ln the torni selected to illustrate the in vention there is a stationary frame work comprising two stationary parallel end frames Il, 2 mounted upon a base 3. These end frames may be secured in ditterent ways'butby preference they are held by tout, tic rods il, supported '1n arms `5 integral with the frames and extendingr beyond thc circumference ot the screen which will presently bc described.

For convenience a number ol' man holes il, herein shown to bc circular in lorln are removably secured in thc end trames. In cach end trame there is. a number, preferably four, ol' anti-friction rollers i' ior supporting' the screen rings The precise manner ol. mounting these rollers immaterial but in the preferred form, they are supported upon studs i), the inner ends of which are supllortcd directly in the frame, the outer end being supported in a plate ll). iaid plates are here shown to be circular in form and fitting into the corrcspomling rccesses in the outer iaces olf the end frame. As a .result ol" this construction, the studs are rigidly supported at both ends and the rollers are entirely closed.

'lhc gear rings, mcntioiwd1 support and may bc regarded as `formingr a part of the revolving: screen in which thc desiccation talles place. lhe sides 11 of' the screen consist preferably o'l copper cloth ol a very line mesh, `for example, l0() or liner. This cloth supported upon a suitable 'frame work. which accordiony to the present design consists ol' a number ol' longitudinal bars l2 bolted at the ends to the rings 8 and braced by a number ot rings or bands 13 which support the screen cloth.

Y Means are provided ior rotating the screen slowly, .hc preferred.I means being spur teeth l-l formed upon the screen rings and driven by a pinion 15 mounted upon a shalt lo. Said pinion is fastened to a bevel rear 1T which meshes with a bevel pinion 1S 'fastened to shaft 1l) jourualcdin brackets il() located upon the end 4frame at one end ot' the machine. Shaft il) may bc driven in any suitable manner, for example, the band wheel 2l, scc Fig. 2.

At ont` end of the machine, which for convenience will be termed the front cud, are atomizers 22. These are preferably two in number located cqui-distantly on opposite sides ot the axis of rotation otfthe screen. 'lhcmilli or other product to be desiccatcd forced' into said atomizcrs through pipes i223. The atomizcrs are preferably supported in the iframe and are therefore stationary and may be ol any suitable Imttern, the eS- "sential characteristic being that they shall be capable oi sub-dividing the millt into a SCE l ha n.

VHaring thus described my invention, what l claim as new and desire to secure by Letters Patent, is:

l. A desiccating machine comprising a substantially cylindrical dust iizollccting screen revolving about a substantially horizontal axis, a vacuum head located within said screen and haring its receiving mouth close to the internal snrt'acc ol' the screen nar the lowest point thereof, and a duct leadingfrom said vacuum head and passing out through the cnd of `said,scria\n` l'or removing the solid particles therefrom.

:2. A desist-.ating machinecomprising a revolving screen closed at the ends and rerolring about a substantially horizontal axis, an atomizer 'For intimincing [luid into said screen, and a stationary racuuin head within said screen, said vacuum head pra ctically touching the inner surface et' the screen For orcibqY withdrawing particles lodged against it.

3. A. lesiccating machine comprising a re relying screen, an atomizer discharging ther-cinto, a Innlti'scction vacuum head within said screen lor withdrawing the desiccated material and. a conveyer duct communie-ating with the sections of the vacuum head and leading' to the exterior ol the inachine, dill'erent portions ol said duct being olldill'erent diameter for rendering the suction ithin the various sections of the vaeu` um head uniform.

el. A desiccating machine comprising a revolving screen arranged approximately horizontal, stationary end fames for said screen, geared screen rings l'or rotating said screen, anti-friction rollers for supporting said ring upon said end frames, and an atomizer deliveringr through one of said end 'frames for introducing fluid into said screen.

5. A desiccating machine coniprising a revolving screen, imperforate end frames, an atomi/,er supported in one of said end frames and discharging into said screen, an air duct supported in the other end frame for delivering air into said screen and means within said screen for automatically removing the contents thereof. i

A desiccating machine comprising a revolving screen having a substantially horizontal axis and composed of foraminous material oi. line mesh for retaining high comminuted particles oi solid matter, stationary end frames for supportin said screen, an atomizer delivering throngi one of said end frames, an air blast delivering through the opposite end frame, and means for sucking the desiecatcd material from the floor of said screen.

In witness whereof, I have hereunto subscribed Iny name in the presence of two witnesses.
